About 1 year and 6 months ago...? When I first started learning web development, I was recommended to listen to a lecture by a famous developer. At that time, I couldn't understand the lecture content at all no matter how many times I watched it, so I gave up halfway through. Then, I got a job at a company and worked for about 1 year and 6 months, and then I remembered it and started listening to the lecture again. Now, after such a long time, I finally understand the teacher's lecture. I feel like I've grown a step, so I'm touched... My personal review is that although it's an introductory course, it can be quite difficult for beginners. I think that it would be better to have some experience with web development or study it before you can understand what he's talking about. I hope that no beginner developers will be frustrated by this lecture like I was 1 year and 6 months ago. Even beginner developers who have difficulty understanding this content now will naturally understand it later with just a little effort, so I hope you don't get too frustrated or blame yourself for not having talent in development. Thank you for the great lecture. Mr. Baek Gi-seon. I have also applied for the next lecture, so I will see you in the next lecture!
